CAS 118-82-1: 4,4′-Metilenbis[2,6-di-terz-butilfenolo]

Descrizione: 4,4′-Metilenbis[2,6-di-terz-butilfenolo], comunemente noto come MBT, è un composto organico caratterizzato dalla sua struttura, che presenta due unità di 2,6-di-tert-butilfenolo collegate da un ponte di metilene. Questo composto è utilizzato principalmente come antiossidante in varie applicazioni, in particolare in plastica, gomma e lubrificanti, per prevenire la degradazione ossidativa. Il MBT mostra alta stabilità termica e proprietà efficaci di cattura dei radicali, rendendolo prezioso per prolungare la vita dei materiali esposti al calore e all'ossigeno. È tipicamente un solido a temperatura ambiente, con un punto di fusione relativamente alto. La presenza di gruppi voluminosi di tert-butilo aumenta il suo impedimento sterico, contribuendo alla sua efficacia come antiossidante. Inoltre, il MBT è noto per la sua bassa volatilità e buona solubilità nei solventi organici, il che facilita la sua incorporazione in varie formulazioni. I dati di sicurezza indicano che, sebbene sia generalmente considerato a bassa tossicità, è necessario osservare misure adeguate di manipolazione e sicurezza per ridurre al minimo l'esposizione.
